I'll relate my experience with Rotel RCD-991. Purchased ex-demo early 2000's. Vinyl was my primary source at the time, so the Rotel served the purpose as secondary source.
Fast forward to 2011 after a break from Audio, decided to purchase a new Digital Spinner, the Rotel sounded like "A Piece Of Crap, to quote the great Neil Young. After sitting unused for three years or so, decided to get the RCD-991 upgraded by Burson, having read positive reports. They upgraded the Clock/Crystal & OPamps. The difference is staggering, the Rotel RCD-991, which was previously unlistenable now comes close to my Unison Research CDE, (using Balanced) the best CD Player I've experienced.
For Aus$350 parts & labour 3 or 4 year ago, the improvement is close to 2k worth in sound quality.
So can't recommend the RCD-991, stock, but if you have access to Burson or equivalent component upgrades, then definitely. Has been a reliable Player also.
